Harmonic Highlights

  • Eb°7 functions as a chromatic passing chord (#I°7 or bIII°7) creating smooth voice leading between the tonic C6 and the supertonic Dm7.
  • The progression relies heavily on extended ii-V7 cycles (Dm7 to G7), establishing a firm diatonic foundation in C Major.
  • Ab7 acts as a tritone substitute (subV/V) or a bII7 chromatic approach chord, providing harmonic tension before resolving to the G7 dominant.
  • The structure follows a traditional waltz-time harmonic rhythm, emphasizing strong-beat resolutions typical of early 20th-century salon music.

Improvisation Focus C Major Bebop scale, incorporating the Eb passing tone to highlight the diminished-to-diatonic transitions.

Difficulty Rating 2/5: The harmonic movements are predictable and the slow waltz tempo provides ample time to navigate the standard chromatic substitutions.
